This product has been discontinued.

This product has been replaced by an improved second-generation version, which can be used as a near drop-in replacement despite its much smaller size.

This discrete MOSFET H-bridge motor driver enables bidirectional control of one high-power DC brushed motor. The little 1.8×0.8-inch board supports a wide 5.5 to 40 V voltage range and is efficient enough to deliver a continuous 20 A without a heat sink.

Some discrete MOSFET based H-bridges are unable to handle a continuously high PWM signal (100% duty cycle). This has to do with bootstrap capacitors not having enough time to charge. Does this bridge allow 100% duty cycle PWM input?
Yes. The design has an extra charge pump that allows the high-side MOSFETs to stay on indefinitely for 100% duty cycle operation.
